PRODUCT DATA

FEATURES

• Pt 1000, BALCO 500 or 20kΩΩΩΩ NTC temperature

sensing element

• Wide sensing range

• Capacitance type sensing element for relative

humidity

• Plug-in design

GENERAL

The H7012A Room Humidity Sensor is a capacitance type
relative humidity sensor for wall mounting.

The H7012B Combined Room Humidity/Temperature Sensor
incorporates a capacitance type relative humidity sensor with
a Pt 1000, BALCO 500 or 20kΩ NTC temperature sensor in
one housing.

These sensors are used for control, indication and alarm
monitoring in room air conditioning installations.
